Comic retailers entered 2014 optimistic about the future, after a 2013 that saw increases across formats, genre, and channel, according to a new report in ICv2’s Internal Correspondence #84. The broad-based growth, however, did not preclude some concern about trends that direct market retailers feel hold risk for 2014.

There’s some hope among savvy retailers that publishers will avoid the over-production that has dampened earlier booms, although the concern remains.

The overuse of limited variant covers, especially tied to order levels that some called "impossible," was decried, and there are indications that the aftermarket for variants may be softening in the face of the large numbers being produced, some said.

Media exposure continues to drive sales, with The Walking Dead off the charts, and shows like My Little Pony, Teenage Mutant Ninja Turtles, Adventure Time, and Bravest Warriors all driving sales. Adult-targeted live action superhero shows, on the other hand (Arrow and Marvel’s Agents of S.H.I.E.L.D.) have yielded little in the way of graphic novel sales.

Beyond The Walking Dead, Image’s non-media creator-owned titles are also selling, with some seeing an industry-altering dynamic in the trend.

Manga sales appear to be picking up in comic stores, with the impact of Kodansha’s Attack on Titan a significant factor. The strength of that relatively new series produced the biggest shake-up in years in the Internal Correspondence Top Properties charts for the Fall selling season (September through December): Attack on Titan knocked the mighty Naruto out of the top spot on the manga charts after a run at #1 that began in 2005, nearly a decade ago.
